Claims12
A compound of the formula
- and salts thereof.
A metal-organic framework building block comprising a compound of the formula A
- and a metal, the metal-organic building block being robust, non-catenated, 3-dimensional, and permanently microporous.
A process for the preparation of a metal-organic framework of formula [Zn2(A)(B)2]n, wherein n is about 22-about 100, A is a tetratopic carboxylic acid, and B is nothing or selected from R-pryidinal-4-yl and DMF, where R is selected from H, methyl, ethyl, ethenyl and CF3, the process comprising:
- a) solvothermal reacting of the tetratopic carboxylic acid and Zn(NO3)26H2O in DMF;
- b) optionally heating the product in a) under reduced pressure to remove the DMF;
- and
- c) optionally soaking the product in b) in a solution containing A to afford the metal-organic framework.
